Application March 7, 1955, Serial No. 492,650 8 Claims. (Cl. 144 144This invention appertainsbroadly to joinery and more particularly to anovel means for facilitating the accurate .fashioning of planks and thelike for the building of boats and other structures.

Owing to the longitudinal curvature of a boat from bow to stern, and thetransverse curvature from gunwale to keel, much difliculty isexperienced in the fitting of planking to the hull and this condition isaggravated where the planking overlaps, as in clinker built boats. Thusthe longitudinal edge of the planking which is overlapped by the nextadjacent piece of planking must be beveled on a compound curved tocorrespond to the longitudinal and transverse curvature of the boat.Obviously, this requires the skill of an expert artisan.

It is, therefore, one of the primary objects of my invention to providea novel rotary plane for use in combination with a jig and a templatefor the plank or work, the plane being constructed in such a manner thatthe same is accurately guided by the jig and template to give the plankor work the desired bevel by the mere sliding of the plane back andforth by an operator.

Another salient object of my invention is the provision of means wherebytemplates of different charactersfor different boat planks can bereadily associated with the A further important object of my inventionis the provision of a rotary plane having a supporting guide associatedtherewith for movementin a longitudinal guide track forming a part ofthe jig and located adjacent to the table for the plank or work, theplane being mounted for universal movement on the supporting guide, theplane also having a guideshoe arranged in spaced relation to thesupporting guide for travellingmovement over the template, the guideshoefunctioning to tilt the plane on the supporting guide during theslidingmovement of the plane along the jig and over the plank or work.

Another further important object of my invention is the provision of anovel supporting guide for'the rotary plane for sliding movementover'thework and along the guide track, the plane being mounted forrocking movement up and down on the supporting guide and around anaxisparallel to the longitudinal axis of the rotary plane, whereby theplanecan be tilted in the desired directions by the guideshoe as the sametravels over the varying curvature of the template.

A still further object of my invention is the provision of means forinitially adjusting the rotary'plane 'on its supporting guide toregulate the depth of cut of the knives.

A still further object of my invention is to provide a novel rotaryplane for beveling the edges of planks and the like of the abovecharacter, which will be durable and efficient in use, one that will besimple and easyto manufacture and one which can be manipulated .bynonskilled workmen. I i

With these and othenobjects in view,,th,e invention consis'ts in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described and claimed and illustrated inthe accompanying drawings, in which drawings,

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the severalviews,the letter P generally indicates my improved rotary planer for usein conjunction with a jig J for operating on a piece of work W.

The jig J comprises a base 10 and this base preferably includes a baseplate 11 having secured thereto spaced parallel longitudinally extendingsupporting walls 12 and 13 for a table 14. The work W is placed upon thetable 14 so that one longitudinal edge thereof is substantially flushwith the wall 13, as best shown in Figure l. The wall 13 not only formsa support for the table, but also functions as a guide for the rotaryplaner P and consequently, this wall has secured thereto alongitudinally extending guide track 15 and this track extends theentire length of the wall 13. The track is so fashioned as to form inconjunction with the Wall 13 a'longitudinally extending guide slot 16,which opens out through the upper.

end of the jig. It is to be noted that the guide track 15 terminatesslightly below the upper surface of the table 14. 7

By referring to Figure 1, it can be seen that the base plate 11 of thejig extends forwardly of the wall 13 and detachably associated with theforward edge of the base plate 11 in spaced relation to the wall 13 is atemplate 17. I

Now considering that the work W is a plank of a boat and that onelongitudinal edge of the plank is to be beveled on a compound curve, soas to conform to the longitudinal and transverse curvature of a boat,then the template 17 has its upper edge 18 fashioned to agree exactlywith the bevel to be placed on the piece of work W. A template 17 isprovided for each plank of a boat.

Now referring to my improved rotary planer P,. the

same includes a casing 20'having rotatably mounted therein and extendingtransversely thereof a cylinder 21 can be rapidly rotated when anelectric circuit is closed through the r'n'ot'oi 23. Any desired meanscan be pm: vided for driving the cylinder 21 from themotor, but asillustratedthe armature shaftof the motor has secured thereto a sprocket24" and the shaft for the cylinder has secured thereto a spr'o'cket 25'.A sprocket chain 26 is trained over the sprockets 24 and 25.- A guard 27is rigidly secured to the base 20' for the sprockets and-the sprocketchain. p provided for manipulating the planer and the planer providedwith other adjuncts, such 'asa laterally extend ing hood 29 for the woodbeing planed. The parts of the planer, jtist described are common inrotary planers now on the market, and hence, these parts have not beendescribediri detail, and the invention resides in novel means associatedwith the base of the planer so that the planer can be associated withthejig J and guide forthe jigand the template for giving the desired andcorrect bevel to the longitudinal edge of the work W.

Referring to theimprovements on the planer, the same embody a guideshoe30 for traveling movement over the edge 18 of the template .17. The shoe30 preferably includes a block 31 having a polished lower face for engaging the edge 18 of the template and this block is removably securedby a bolt 32 or the like to a bracket 33 and this bracket is in turnrigidly bolted to the guard 27. The opposite end of the frame or casingof the rotary planer P has associated therewith, in a novel manner,guide brackets 34 which cooperate with the work W, and the guide track15. The guide brackets 34 are of an angle shape in side elevation andare arranged in A suitable manipulating handle 28 is spaced relation toone another aridare rigidly fastened to a Iongitudinallyextendingsupporting bar 35. Each bracket 34 includes an upper arm 36, whichslides over the upper face of the work and 21 depending right angularlyextending arm 37, which slidably seats in the guide track, i. e., theslot 16. In order that the planer P will have universal movementrelative to the brackets 34, a novel connection is bad between theplaner and said brackets 34 and theircross bar 35, and this connectionconsistsof the following: One ,side of the base or frame 20 of theplaner P around the shaft of the cylinder 21 is 39 is provided at itsopposite sides with laterally extend ing arms42 and 43. The arm 42 isconnected by a hinge 44 with the bar and it is to be noted that thishinge 44 includes a leaf '45, which is riveted or otherwise secured tothe bar and a leaf 46 which is connected to the arm 42 by a pivot 47;Thus, the arm 42 and consequently the plane itself can swing up and downon the bar 35 and also rockon the pivot 47.

The arm 43 is connected to the bar 35 by means of a hinge 48 and thishinge includes a leaf 49 which is riveted or otherwise secured to thebar 35 and a leaf 50 which is adjustably connected to the arm 43.Theconnection of the arm 43 with the leaf 50 is best shown in Figures 7and 8 of the drawings. As illustrated, the arm 43 rotatably carries anadjusting screw 51which is threaded in a'traveling block 52. Thisblockin turn is rigidly fastened to the leaf 50 by a screw 53 orthelike. The traveling block has formed thereon laterally extending cars54 which snugly engage a part of the arm 43 and these cars form guidesfor the block during the adjustment thereof. By turning the screw 51,theplane can be swung on the pivot 47 so that the cylinder 21 and its.

1 4- A knives 22 can be adjusted relative to the work without thenecessity of adjusting the knives in the cylinder.

In operation, the desired template 17 is secured to the jig and the workW is laid on the table 14 with one longitudinal edge thereof flush withthe vertical face of the wall13. The work can be temporarily secured tothe table in any desired way. The plane P is now placed in position onthe jig, with the guide brackets 34 so placed that the arms 37 willslide freely in the guide slot 16. The horizontal arms 36 of the guidebrackets engage the top surface of the work and the guideshoe 31 isrested on the edge 18 of the template. The plane P can now be slide backandforth over the work to bevel the longitudinal edge thereof and as theplane travels over the work with the shoe following the contour of theedge 18, of the template 17, the plane will rock on the hinges 44 and 48and will turn in the ring 39. Thus, the plane will follow the exactcurvature of the edge 18 of the template and bevel the longitudinal edgeof the work in exact accordance with the form of the template.Obviously, the plane is carried by. the brackets 34 for universalmovement and while I preferably use the ring 19 to permit turning of theplane on the. brackets, it is to be understood that other types ofpivots can be utilized to connect the brackets with the plane.
